Intel P4 Socket 478 CPU Overclocking

[optimus]

Can anyone tell me what the best 478 CPU was for overclocking?

 

[Sone]

the first 1.8 northwoods were nice clockers. 2.4ghz minimum even with stock cooler

Any M0 stepping Northwoods, usually came at 2.4, 2.6 and 2.8Ghz.

I reached 4 ghz on my 3.0 ghz scott with a zalman 7000-alcu cooler...

The old 478 Northwood 3.06 ive just removed from my old machine had been running 3.4GHz with no problems for about 4 years.

Ocassionally id try to get it a little higher but end up with system hangs eventually.

Been a damn good chip that has! Just a shame the FSB was a little 'outdated'

Get the fastest northwood you can find.

Yes! I have one of these sitting around - (30 cap 2.8). Ran fine @3.5 and *nearly* stable 3.8 under watercooling.

2.8MO...had it running @ 4.2 ghz without any probs with my mach 2 gt...

if you want a prescott then get a D0 stepping..results-> check sig

Out of interest, how good is performance on your cpu? pcmark04/05 score or 3dmark 05/06 cpu score please ?

Didnt know them 478 chips had so many juice in em, I know higher rev. 65nm scots for lga775 can reach 7 + ghz on mach2, but never seen a 478 scott that high...

My oc limit was 4.0 ghz on both my old 3.0 scott, and old s478 3.4 scott, mainly due to to high temps, mine were 72 C on load , as said above though, that was on a zalman 7000-alcu.
